JPF is a file type used to store and compress digital images. It is based on the JPEG-2000 format, which is an improved version of the JPEG format. JPF files are commonly used for storing high-quality images, and they offer features such as lossless compression and high-resolution support.
A WEBP file is an image saved in the WebP (pronounced "Weppy") raster image format developed by Google for web graphics. It is designed to reduce image file sizes over standard JPEG compression while maintaining the same or similar quality. WEBP files allow images to be downloaded more quickly.
